U. ALLEN,

My invention relates water 2163::

monly insralled in other places Where not be supplied at irremi The chief objects which eonsiiiute the .1 applieution for pm: Writer boiler so eon, ally large perceuiag utilized to ilings hoiels or ements of ihls coingyaratiwly s1 the reserve i toot Wiih the arms ing surface 21 one iinie, W

available quantity of hot or he quickly first furnished ation of the .s ition are to i t .y be employed Wiih any boiler u: ijliose in-coini'non use giving econo results Whatever the character of? ihe fuel supplied to the burner, which maybe adapted to burn oil or gas; and as the burner, owing to the manner of applying the flame and conserving the heat supply, may be of comparatively small size, and is-placed beneath ilie tank, there is a marked economy in the amount of space required.

The above and other minor results are obtained by employing the aggiaraius illusirated in the accompanying drawing which forms a part oiibis application, the details of construction being shown in the following views Figure l vertical median section Water heating tank, embodying improvements; Fig.2 is a partial top plan View of the apparafcus;-ancl Fig. 3 is a top plan View "with the heat retainingmember removed.

Referring to the details of the drawing, the numeral 5 indicates an upright tank resembling in a general Way the reservoir usually-installed in domestic Water heating systems. The said tank or reservoir is supported in the ordinary manner upon a suit DIOVi de a i end 17, en?

able base 6, and has e top i" and a bottom 8.v Extending vertically between the top and bottom plate is a iiue 9, preferably located concentrically with the tank walls and having its ends projecting ihrough openings in said plates the margins being upset or turned outwardly i0 form retaining flanges 10. The usual connection shown at 11, and a drain pipe 12 is iached at she bottom as in all boil if this iypei The ropoi ihe boiler is 1' rnished with the usual 15$ for cmineeiion will: the hob ier pipes of the dislrihui ing sysrein. v iiaiely below the fine is located b r which, may be of f any form but is nref hiymade round and of cl.ia'*ieter to correspond}with ihe size oi [wronged W l 15 i 1 in its lower eonneeted Will the boiler nea been In, Whi he no boiler n 1 flue. @a through jhe 18, iernnnai and i'iaving a dislabzach d to the u upon e nan the shaft 18 so reaches io ilie lower one i pro 'ided 6. above the g smoke and on of the devi economy in bile ii line will be ii u? by those ed in the art to which inveniion pertains The eoil l5 c. oonsiiilerablo lengih and. n iii-1e nur row annular space between the inner aii the ilue we the oylinilrioal heal; retainer 18, will presono 2i eo npo aiiively l ascending-ho said. fiang holes 21 cri ieof h burner to the action of the Wafer therein will be quoiriy h ied, producing n constant nurrenithrough the coil and as WEIi'Gl circulating through this coil is til zen from below and enters the top of the mni: its lighter specific grai 'ity will cause it to displace the colder water remaining at the top ready to drawn oil through the hot Water pipe. The tube 18 will present a considerable mass to the hot current through the flue, and when once raised to the maximum degree of heat, it

will remain at a constant temperature so long as the flame remains 1iIlCllIl1iHiSil(-3l, and when the latter is turned down or put completely out the heated tube, being in contact with the coil or in close proximity thereto, Will give ofi a large proportion of its heat to the latter, so that the water Will 0001 more gradually than would be the case if equivalent means for thus storing the surplus heat Were not employed. The purpose of the lower conical end of the core 18 is to spread the flame from the burner and direct it into the annular space occugiiecl by the coil. c

The cavity of the tube 18 is packed with a heat retaining substance, thus causing the members to radiate its heat snore slowly than if made entirely'of metal, and for thifilling I prefer to use asbestos in some of its forms, such material being indicated 18 Having thus described my invention, What I claim as new, i

1. In a Water heater, the combination with a tank having inlet. and outlet openings and an open ended flue extending therethrough, of a Water coil" arranged in said fine and communicating directly with the upper anti lower portions ofseid tank, a flame spreading and heat retainin member suspended in the coil extending t e length of the fine and consisting of a tube closed at its lower end, and means for supplying heat to said flue, coil and heat retaining tube.

2. In a Water heater, the combination with retaining member, col arranged wit-inn the coil, and e permea ion on the upper end of the core engaging the margin of the tine, and means for supplying to said tiue, coil and sore.
